The pros and cons of floating wind turbines

I am a strong supporter of renewable energy. And mostly I prefer offshore wind power.

Professor Tore Undeland, from NTNU, in 2014 was saying that, Wind power could cover Norway’s energy needs 20 times.

I believe that many other countries have similar opportunities.

Most common wind turbines use bottom-mounted towers. They are easy to install, have low maintenance cost and have a long life span. But there is a major disadvantage to them: they can be installed in relatively shallow waters.

For deep waters there is an alternative solution: floating wind turbines.

The biggest advantage I see, for owning such units, is the mobility. They can be built on land, in assembly lines, and transported to various locations. For repair they can be brought back to land.

More, floating wind turbines can be designed considering product lifecycle management. Meaning that they can be made upgradable and fully recyclable.

See also the Wikipedia page on this subject.

The main disadvantage of this solution is that is not completely understood. A lack of a histogram for a large number of such projects bring forward the “risk of the new”. Not knowing all the risks involved will make investors less interested and the market boom of the floating wind turbines is yet to happen.
